OIL-BURNER.

To all whom it may concern:

Be it known that I, BERNARD S. FEINER a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented cer- Burners, of which the following is a specification.

My invention relates to home gas makers,

and the primary objects contemplated are the provision of a novel form of retort disposed in immediate proximity to the burner cap so as to effectively pre-heat the oil and provide for complete vaporization; the pro:

vision of a dead-air space as a component part of the burner cap in furtherance of the pro-heating principle: and the construction and arrangement ofthe various parts of the device to permitof' ready and rapid dissembling, and particularly to improve the To the accomplishment of the recited ob jccts and others coordinate therewith, the preferred embodiment of my invention re 7 sides in the construction and arrangement 'Fig. 1..

shown in the accompanying drawings, hereinafter described and embraced in the scope of the appended claims.

In said drawings:

Figure 1 is a top plan view of two of the burners embodying my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a vertical section, on line 3 3- of Fig. 2, of the burner ;and support.

Fig. 4 1s a vertical sect1onal elevation of the burner cap and burner, on line 44 of Fig. 5 is a transverse sectional view taken along line 55 of Fig. 2.

Fig. 6 is av perspective view of the base plate.

Fig. 7 is a perspective view of the burner and its tube.

Generally speaking, my invention comprises a burner cap formed of top and bottom sections and an intermediate mixing chamber which cooperates with the lat er to form a dead-air chamber. The bottom of the cap proper constitutes the bottom of the dead-air chamber. and at this bottom is adapted to lie the retort. The heating principle is carried out by the novel formation of the tube leading to the burner, the same running first upwardly then coiled about the bottom of the burner cap, then returning in Specification of Letters Patent.

a downward direction, and finally being disposed in parallelism with the circular portion and in substantial continuity with the main lead portion of the tube. The burner proper is located upon the last mentioned extremity of the tube. The burner cap, burner and base plate are formed so that they may be readily assembled or dismantled when occasion requires, and in this particular it will be pointed out that the burner cap is preferably seated upon a plurality of up rights which extend from the base plate and that consequently the burner cap as an entirety may be removed fonobvious reasons from its normal position.

In the drawings the numeral 1 designates the burner cap. which is formed of a lower cup-shaped section 2 and an upper convex I baflie plate 3, the two component parts being detachably secured together, as at 4:. The bottom section 2 is provided with a central circular opening 5 designed to receive a hollow shank portion or mixing chamber 6, the two being provided with complemental thread portions to serve as securing means. The mixing chamber G flares out into an upper portion 7 which is disposed in a horizontal plane. and this in turn is deflected in vertical parallelism with the main shank and at a sullicient distance therefrom to form a space. as 8. Tn this connection it Will also be noted that the bottom of the section 2 of the cap is formed with projections 9, the purpose of which will be hereinafter eX- plained.

As exhibited in Figs. 1, 2 and 7 of the drawing. it will be seen that the burner tube or pipe 11 has first'imparted to it a rightangular bend thus forming a comparatively short vertical portion 12. The tube is then continued in the for-m of a coil, as 13,which is styled the retort or generator, and is seated upon the projections 9 and-eventually terminates in a return bond 14.- parallel tO its companion bend l2. Medially of the lower portion we preferably mount a tip 15 Whichupon inspection of Fig. 4 will be found to y axial plane of the mixing chamber. Upon opening any suitable valve in the supply pipe 12 to permit the oil under pressure to pass through the burner tube, and igniting the combustible mixture, the resulting flame will pass upwardly and strike the u per bafile plate3 of the burner cap and be de ected outwardly through the perforations 2" of the bottom section of said cap.

A cardinal feature of my invention relates to the provision of means for conducting air up to the burner tip in the shank 6 and for this there is provided an extension or nipple 30 which is detachably connected at apertures 31 to the pan 32 of the frame 25. The nipple is of such length as to fit ,telescopically within the neck of chamber 6 so that a good sliding fit is secured enablin .the whole burner top to be readily lifte from the supports 24 and the nipple 30.

The nipple 30 is threaded at its lower end to receive upper and lower nuts 30 whereby it may be set in adjusted position. The upper end of the nipple is notched at 30 to receive arms of the burner 16 and the lower end of the downwardly extending neck of chamber 6 is similarly notched at 6 to slide over the arms and telescope upon the tube 30. In this manner not only is the' burner positively supported but it is also incased in an air intake tube, as 30, which opens at a considerable distance below the point of combustion and thus insures, by

the up draft from below, combustion above the burner tip and nipple 30.

What is claimed as new is:

1. In a device of the character described, the combination of a burner having an inner mouth piece with an inverted flaring flange,

a perforated shell having a central aperture to which said mouth piece is attached and forms a closed annular space, a cap for the shell and forming therein a mixing chamber, a fixed nipple having an open lower end and upon which said mouth piece is fitted, and a burner tip arranged to discharge into the mouth piece and disposed in said nipple above the'open lower end.

2. In a device of the character described, the combination of a burner having an inner mouth piece with an inverted flaring flange, a perforated shell having a central aperture to which said mouth piece is attached and forms a closedannular space, a cap for the shell and forming therein a mixing chamber, a fixed nipp e upon which said mouth piece is fitted, a burner tip arranged intermediately said mouth piece and the nipple, and a support to which the nipple is adjustably attached.

3. In a device of the character described, a burner having a combustion chamber having a downwardly extending intake connection, an upwardly extending nipple telescoping in said connection, and'a burner tip disposed between said connection and the nipple.

4. In a device of the character described, a burner having a combustion chamber having a downwardly extending intake connection which is notched at its end, an upwardly extending nipple telescoping in said connection, and a burner tip disposed between said connection and the nipple, the nipple having notches registrable with those of said connection, said tip embraced in said notches.

In testimony whereof I affix my signature.
